Jonathan Elliot, Debates in the Several State Conventions on the Adoption of the Federal Constitution (1907)
“ It is well known that the subject of revenue is the most difficult and extensive in the science of government: it requires the greatest talents of a statesman, and the most numerous and exact provisions of a legislature. The command of the revenues of a state gives the command of every thing in it. He that hath the purse will have the sword; and they that have both have every thing; so that Congress will have every source from which money can be drawn. ”
